Abstract
Coatings containing high-temperature phases of tungsten borides W2B and β-WB are obtained on titanium and steel targets by a shaped charge explosion. In some regions of the target, microhardness achieves ≥42 GPa. The phase composition of different regions of the coatings is examined by X-ray diffraction. The values of unit cell parameters indicate the formation of phases with variable composition. The crystal structure of β-WB is refined.
